  • A discrete heat map consists of cells colored according to their data values. It is the counterpart of the continuous heat map, also known as the contour chart.

  • Discrete Heat Maps can have different shapes simply by leaving some cells empty.

  • The cells can have labels that show their data values or some other custom information. There can also be gaps between cells.

  • This example uses legend entries to label the colors instead of a color axis scale.
  • In ChartDirector, discrete heat map is implemented as a layer of the XY chart. That means other layers can overlay on the discrete heat map layer. In this example, the symbols in the cells are adding using scatter chart layers.
